Hi, I have just got my first Pay as you go 3G iphone on O2 and have some Q's that people may be able to help me with: 1. I have access to internet through wifi at home but when out and about can I not access internet on 3G for free for the first 12 months? If so, how do i set that up as I couldn't get online yesterday when in the pub? 2. What is VPN? 3. What is Jailbreaking? and quick pro's and cons of doing so? 4. Any do's and do not's? Thanks.
